Doubly-linked list.
List contains its own specialized merge-sort (see sort()), though the generic sort functions can still be used (see SortedCollection::sort()).
Attributes
Note that when you set keepSorted = true, you also implicitly set sorted = true. Likewise, when you set sorted = false, you implicitly set keepSorted = false.
Performance Considerations
Remember that setting keepSorted = true imposes a performance penalty. If you don't require the list to be sorted, make sure it's set to false. Also, even if you do need the list to be sorted, you may be able to set keepSorted = false.
Consider this code:
Since the tree's objects are sorted, and the list will have the same ordering, we know the list is sorted. Having keepSorted = true would have been pointless, unless we wanted our list to have an ordering different from our tree's. Even in that case, it would likely be better to leave keepSorted = false, and just sort() the list after copying the tree's objects. Batch processing is usually more efficient.
